MS 4A was employed as an acid scavenger to avoid deactivation of the guanidine catalyst by acidic impurities which would be accidentally generated via partial hydrolysis of diphenyl phosphite (3). The reaction stopped in low conversion without MS 4A. For MS 4A as an acid scavenger, see: (a) Weinstock, L. M.; Karady, S.; Roberts, F. E.; Hoinowski, A. M.; Brenner, G. S.; Lee, T. B. K.; Lumma, W.
